This morning the view towards the entrance of Bergen harbour looked like this. The ugly, purple, smoke-like structure you see in the background is due to a phenomenon called inversion. According to Wikipedia this is:

"In meteorology, an inversion is a deviation from the normal change of an atmospheric property with altitude. It almost always refers to a temperature inversion, i.e. an increase in temperature with height, or to the layer (inversion layer) within which such an increase occurs.[1]

An inversion can lead to pollution such as smog being trapped close to the ground, with possible adverse effects on health. An inversion can also suppress convection by acting as a "cap". If this cap is broken for any of several reasons, convection of any moisture present can then erupt into violent thunderstorms. Temperature inversion can notoriously result in freezing rain in cold climates."

Many, many years ago, I skied at Jackson Hole, WY and they frequently had temperature inversions which did some strange things - the temperature at the TOP of the mountain would be zero C and at the bottom, -25C. There wasn't much vehicle emissions, but tons of smoke from wood burning.

There is so much petulant, dreary traffic everywhere, so i am going to buy, as would do any responsible citizen, a bright, chrome-plated bicycle. Even your didactic attempt at 'ugliness' is thwarted by your fine sense of color and composition.

I love your blog. One of my life wishes is to visit Norway, love that nature... Your blog makes my dream come true for a few moments through your beautiful pictures and thank you for that :) And while all my friends dream about warm Spain or romantic France I dream about Norway :)Greetings from Serbia and keep up good work :)

In spite of the inversion the picture of the the boat knifing across the still water is very beautiful.

But I have a question. On our TV this evening was a brief clip of people in Norway running alongside rabbits on a leash. The rabbits were hopping over little obstacles like horses at a steeple chase. Is this really a sport in Norway? It was funny.

I'm sorry to see this ugly event happening in beautiful Norway. It was my understanding that scientists in Norway had invented of a way to capturing and burying carbon emissions in the sea...so far the only ones making an effort at solving pollution problems..

Great capture! We get inversion in Johannesburg, South Africa too but it is not often you can get to a vantage point and capture it as nicely as you have done. That harbour is beautiful in itself, isn't it?

Inversion seems to be a fact of life in almost every place around the world ... saw plenty of it in Turkey ... noticeable in particular when flying in and out of big cities. So sad that we don't take better care of our world.
